Hill Arches is a bronze sculpture by Henry Moore, catalogued as LH 636.
The piece is made of four separate parts, three of which are described by Roger Berthoud, Moore's biographer, as being stirrup-shaped; the fourth is a large sphere.
One cast is situated in the Karlsplatz in front of the Karlskirche in Vienna, where it was installed in 1978 â initially to complaints that it disrupted the views of the historic church. Another is sited at the headquarters of Deere and Company in Illinois.
